In between the time when Sony Mobile officially tweeted that they are going to release their android 4.4 KitKat and android 4.3 update plans for the Xperia devices, a new firmware has been spotted for T-Mobile USA Xperia Z C6606/C6616. 10.3.1.E.0.191 firmware besides 10.3.1.E.0.190 firmware has been spotted on PTCRB website recently.

It is still not clear that 10.3.1.E.0.191 firmware belongs to which android version. It is a higer build over android 4.2.2 10.3.1.A.2.67 firmware update as the new firmware has a new series 10.3.1.E.X.XXX so it is expected to be a higher build of android too.

[ UPDATE 19 Nov ]

T-Mobile Xperia Z Android 4.2.2 10.3.1.E.0.191 firmware update rolling finally

Check below the certification of 10.3.1.E.0.191 firmware on PTCRB website. 10.3.1.E.0.190 firmware can also be seen in below image.

10.3.1.E.0.191 firmware certified for Xperia Z

No new firmware has been spotted for global Xperia Z C6603 LTE and C6602 HSPA+ versions, it something amazing that we saw a firmware certified for T-Mobile USA Xperia Z version.

We hope it may a higher build of android, hopefully android 4.3; still no official word on this. As soon as we get more info on this new firmware certified, we will update you…

Let us know if you have received any such firmware update…
